Executive summary:

Under the conditions of this study a density of 0.722 g/cm3 at 15°C was determined for the test substance, Hydrocarbons, C7-C9, isoalkanes.

Description of key information

The density of hydrocarbons, C7-C9, isoalkanes is between 0.65 and 0.75 g/cm3.

Key value for chemical safety assessment

Relative density at 20C:
0.72

Additional information

The measurement of density or relative density of petroleum distillates by digital density meter is covered by method ISO 12185. A test conducted with this method by ExxonMobil Chemical (2010) determined the density of hydrocarbons, C7-C9, isoalknes to be 0.72 g/cm3 at 15°C.
